Contaminated Atmosphere SWMS

Product Description

Working in areas where airborne contaminants may be present requires careful planning, exposure monitoring and effective control measures to protect workers from hazardous substances. The Contaminated Atmosphere SWMS is intended for demolition contractors, construction businesses and principal contractors undertaking work where exposure to contaminated or potentially contaminated atmospheres may occur. It helps businesses safely plan, manage and document activities involving airborne contaminants while supporting site-specific risk management and compliance with Australian WHS requirements.

Construction and demolition activities can expose workers to a range of hazardous airborne contaminants generated through cutting, drilling, demolition, welding, plant operation and material handling. Without appropriate controls, exposure to respirable dusts, fumes and other airborne hazards can present significant health risks. This SWMS establishes a structured approach to identifying potential atmospheric contaminants, implementing suitable engineering and administrative controls, selecting appropriate respiratory protection and maintaining safe work practices throughout the project.

Rather than focusing on a single work activity, this SWMS supports businesses performing a variety of construction and demolition tasks where hazardous airborne contaminants may be encountered. It provides a practical framework that can be reviewed and customised to suit individual workplaces, environmental conditions and project requirements.

Activities Covered

• Assessing work areas for potential airborne contaminants.
• Planning work involving contaminated or potentially contaminated atmospheres.
• Selecting appropriate respiratory protective equipment (RPE).
• Implementing dust suppression methods.
• Providing local exhaust ventilation where applicable.
• Managing work involving crystalline silica.
• Controlling exposure to lead-containing materials.
• Managing diesel particulate emissions.
• Controlling welding fumes.
• Managing vibration exposure.
• Managing occupational noise exposure.
• Monitoring work areas and maintaining housekeeping.

Hazards Addressed

The documented work activity addresses hazards that may include:

• Crystalline silica exposure.
• Lead exposure.
• Diesel particulate emissions.
• Welding fumes.
• Contaminated or flammable atmospheres.
• Airborne dust.
• Hand-arm and whole-body vibration.
• Occupational noise exceeding exposure standards.
• Respiratory hazards.
• Reduced visibility from airborne contaminants.

Control Measures Included

Depending on the selected work method and project requirements, the SWMS outlines controls such as:

• Respiratory protective equipment selected for the work activity.
• Wet methods and water suppression to minimise airborne dust.
• Local exhaust ventilation where applicable.
• Adequate ventilation in enclosed work areas.
• Engineering controls to reduce hazardous exposures.
• Maintenance of diesel-powered equipment to minimise emissions.
• Job rotation to reduce prolonged exposure.
• Regular inspection and maintenance of equipment.
• Worker training in hazardous substance management and safe work practices.
• Good housekeeping and exposure management procedures.

PPE Requirements

The source document specifies PPE including:

• Hard hat.
• High-visibility clothing.
• Safety footwear.
• Eye protection.
• Dust mask.
• Respirator where applicable.

Additional PPE may be required depending on the contaminants present, exposure levels and project-specific hazards.

Plant and Equipment

Plant and equipment may include:

• Telehandler.
• Local exhaust ventilation equipment.
• Dust suppression systems.
• Respiratory protective equipment.
• Air monitoring equipment where applicable.

Hazardous Chemicals

Where applicable, the work may involve exposure to:

• Crystalline silica.
• Lead and lead-containing materials.
• Diesel particulate.
• Diesel fuel.
• LPG.
• Welding fumes.
• Other airborne contaminants generated by construction or demolition activities.

Hazardous substances should be managed in accordance with Safety Data Sheets, applicable Codes of Practice and project-specific procedures.

Emergency Planning

The SWMS includes emergency response procedures covering medical emergencies, utility strikes, electric shock, fire, explosion and the unexpected discovery of asbestos-containing materials, together with reporting and communication requirements.

What’s Included

This editable Microsoft Word SWMS may include:
